Solid Lubricant Grease with Calcium Sulfonate Complex Thickener Provides Lasting Protection for Heavy Mobile Equipment

Lubrication Engineers, Inc. formulated its solid lubricant-containing, calcium sulfonate-thickened Almamoly® HD Grease for use in severe conditions such as high temperatures, heavy loads and water. This high-performance grease is intended for long-lasting use in heavy-duty mobile equipment such as that used in construction, agriculture, open pit mining and road-building.

Almamoly HD Grease contains Almasol®, LE’s proprietary solid additive as well as 5 percent molybdenum disulfide (also known as molydisulfide or moly). Compared to other solid lubricant-containing greases that rely on moly or graphite alone, Almamoly HD Grease’s synergistic combination of moly and Almasol gives it better wear resistance. This unique combination of solids helps ensure reliable lubrication, staying in place even when the lubricant is squeezed out of the contact zone due to extreme pressure (EP) or heavy shock loading. The calcium sulfonate complex thickener provides additional performance features that make this grease desirable for a variety of extreme conditions.

Proprietary Additive

 N/A LE’s proprietary additives are used exclusively in LE lubricants. Almamoly® HD Grease contains Almasol.

Almasol® solid wear-reducing additive is able to withstand extremely heavy loads, chemical attack and temperatures up to 1,900°F (1,038°C). It is attracted to metal surfaces, forming a microscopic layer but not building on itself or affecting clearances. Almasol minimizes metal-to-metal contact and the resulting friction, heat and wear.

Performance Requirements Met or Exceeded

 N/A
  • Can be used for equipment that requires or specifies greases containing solid lubricants
  • Can be used for heavy-duty mobile equipment requiring 5% moly grease, including Caterpillar®, Hyundai, John Deere® and Komatsu®

Recommendation

 N/A
  • Can be used with automatic single-point lubricators and centralized lubrication systems

Typical Applications

 N/A
  • Large mobile equipment used for agriculture, construction, open pit mining and road-building, including articulated trucks, backhoes, bulldozers, conveyors, crushers, excavators, loaders and shovels.
  • Swiveling and pivoting parts including articulated joints, bucket pins, sleeve bearings, pivot bearings, hinge pins, latches, locks, spindles, threaded parts, cams, and slides.
  • Other applications such as continuous casters, motor-operated steam valves, and underwater applications.
